St Nikolaus im Warndt is the site of many special St Nicholas activites. Since 1967 a seasonal post office opens each year with a new St Nikolaus postmark. St Nicholas cards are also available, recently children's cards, too. St. Nikolaus comes on horseback to the primary school. All the festive Nikolaus activites—the post office, Advent Fair with market, serving coffee and cake, and more— take place in the school gym.
